"It's a way of doing a superhero film within another genre. I wanted to tell an origin tale in a slightly different way. It's part of the Marvel cinematic universe, but it also feels like its own piece," he told IGN.

"I've been collaborating with [Marvel boss] Kevin [Feige] during the whole of that cycle."

He added: "But to be honest, the later I do it, it feels like I could learn more, especially about special effects. It's a big effects movie, so I'm pleased to go into it having done Scott Pilgrim and The World's End because you're always learning more about that side.

"I hope that at some point we'll be able to show that at some venue all finished. Because obviously at Comic-Con we showed it unfinished. All done it looks really good."
